Caps and other parts can be had for it. You may end up paying a few bucks
for them but hey, their good for 20-30 years. Check Highgate for prints.

I just recieved this message from a co-worker of the professor who is
giving me some pdp8/pdp11 stuff. If there is some small VAX stuff
that you're looking for, let me know and i'l see if he has it and
if i can get it. otherwise, if you want something big you come get
it yourself, the stuff is in minneapolis.
by small stuff, i mean like a few memory or expansion interface boards,
etc.
------------------
John Broadhurst mentioned you were interested in some of his old PDP-11
equipment from the Tandem Lab. Thought I'd check, while I'm cleaning
up, if you have any interest in VAX equipment:-) John is still the
major repository, but I have a box of VMS docs I am getting ready to
pitch out. Some dates back to VMS v4, and there is also some media
("Desktop VMS", Online docs, etc) on CD. We also have some hardware we
are (ahem) unlikely to need again: VAXstation 2000s, some newer
VAXstations (3100-era), a historic RRD-40 CD drive, etc.

Sorry for the off-topic post, but this is the best
technical resource there is. Anyway, my company
recently had an IBM Thinkpad 770 go dead. It was
sent for repair and was finally deemed "cheeper to
replace than repair". My office is the official
company electronics/computer dumpster, so it ended
up here. The note stuck to it by the repair place
says "dead motherboard". I have dissassembled it
and now have a nice 15" TFT panel. Now to the
question: What is the interface to this thing?
There are 14 wires going into it. Two are pretty
obviously power for the backlight. They are at
the bottom of the panel and were attached next to
the slide pot that controlled the display brightness.
The other 12 are attached to a connector in about
the center of the panel. The IBM part number is
09J0940.
Thanks

Sure, get a MJ11 memory box (or, rather, 4 times as many MJ11's as you
had MK11's) :-).

I do believe that there's an option to map some of the memory space on the
Unibus into memory space. It probably doesn't work correctly at all if
you're using the Massbus slots for I/O, though, and you certainly can't
get above 124 kWords doing this.
Out of curiosity, why can't you use your MK11's? Not enough power to
run them and the 11/70 at the same time? I had to take multiple 15A
circuits to run my 11/70 with MJ11 memory boxes.

Does anybody know if it's possible to run an 11/70 without the MK11 memory box ?
I know it can be done with the PEP "update", but I was wondering if there is another way, possibly involving standard UNIBUS memory.
Thanks,
Erik.

Watch out - just tuning through certain high-numbered UHF channels is
now illegal, since the cellphone companies grabbed those frequencies and
then a few years later convinced congress that it's illegal for the general
public to tune in to those frequencies.
(As a practical matter, trying to listen to cellphone conversations with
an old TV is really, really tough, though you do get to hear bits and
pieces. Much better are the non-crippled scanners you can buy in Canada
and many other countries.)

I'm getting closer! When I see the splash screen, I hit TAB and saw the
following Award BIOS startup screen:
Award Modular BIOS V4.51PG
Copyright (C) 1984-99, Award Software, Inc.

Your i-opener is undergoing a necessary update. This may
take 30 minutes or more. If for some reason the service
is not working correctly within an hour, please contact
Technical Support at 1-800-298-9525 to report the problem.
Press DEL to enter SETUP

When I hit CTRL-ALT-HOME, I get a "login:" prompt. The HOME,4 combo doesn't
get me a root prompt.
So close, and yet so far!! :-)

I was going to respond to Richard's email but you've said it all
here, Zane. I stand in agreement.

Has anyone else seen this? The only thing I get when I power up my iOpener
is a screen that says "Welcome! i-opener Out of the box. In the outlets. On
the counter. Nothin' but 'Net!" Nothing else. No other screens, or startup
messages. Control-alt-home, or home-4 do nothing.
Any suggestions?

I would have faced them down using BAIT and SWITCH as the cause. Which
is what is being done. I plan to drop in on CC friday after work likely to
cancle
as things is getting to be more of a project if it progresses along the
current
path. I have other projects I need tp put the time to. Unlike some I paid
in full,
so I feel I can demand product under conditions at time of sale, 3/13! All
in all
a big pain.
